Visionary Jane Jacobs, whom I wrote about back in October, passed away this week. I have a soft spot for her work - she was an incredible scholar who remained active to the end. Anyway, I won't write any sort of obituary here since there are far more people out there who can do a much better job, and who already did. But no one, to my knowledge, has contributed more to understanding the organic nature of cities than her. Rest in Peace.
